5. Margaret Mead

'Never believe that a few caring people can't change the world. For, indeed, that's all who ever have.'

6. Robert F. Kennedy

'It is from numberless diverse acts of courage and belief that human history is shaped. Each time a man stands up for an ideal, or acts to improve the lot of others, or strikes out against injustice, he sends forth a tiny ripple of hope, and crossing each other from a million different centers of energy and daring, those ripples build a current that can sweep down the mightiest walls of oppression and resistance.'

7. Mahatma Gandhi

'We must become the change we want to see in the world.'

8. Charles Dickens

'Come out into the world about you, be it either wide or limited. Sympathize, not in thought only, but in action, with all about you. Make yourself known and felt for something that would be loved and missed, in twenty thousand little ways, if you were to die; then your life will be a happy one, believe me.'
